Birds beginning with C

Caatinga Cacholote - The Caatinga Cacholote is a species of bird in the Furnariidae family. It is endemic to the Caatinga in north-eastern Brazil. Formerly, it was considered conspecific with P. unirufa under the common name Rufous Cacholote.

Caatinga Parakeet - The Caatinga Parakeet or Cactus Parakeet is a species of parrot in the Psittacidae family. It is endemic to the Caatinga region in north-eastern Brazil.

Caatinga Woodpecker - Normally, it has been considered a subspecies of the Rufous-headed Woodpecker , but an evaluation by the South American Classification Committee in 2003 resulted in it being recognized as a distinct species. This was based on the differences in habitat, size and plumage, combined with the large distance between the ranges of the two species.

Cab-nary Island Chaffinch - This bird is found only in the highlands of the islands of Tenerife and Gran Canaria. It has two subspecies, F. t. tydea from Tenerife and F. t. polatzeki from Gran Canaria.

Cackling goose - The Cackling Goose , colloquially Lesser or Small Canada/Canadian Goose in North America, belongs to the genus Branta of black geese, which contains species with largely black plumage, distinguishing them from the grey Anser species.

Cactus Canastero - Its natural habitat is subtropical or tropical high-altitude shrubland.

Cactus wren - Unlike the smaller wrens, the Cactus Wren is easily seen. It has the loud voice characteristic of wrens. The Cactus Wren is much less shy than most of the family. Its marked white eyestripe, brown head, barred wings and tail, and spotted tail feathers make it easy to identify. Like most birds in its genus, it has a slightly curved bill. There is little sexual dimorphism. The Cactus Wren primarily eats insects, including ants, beetles, grasshoppers, and wasps. Occasionally, it will take seeds and fruits. Foraging begins late in the morning and is versatile; the cactus wren will search under leaves and ground litter and overturn objects in search of insects, as well as feeding in the foliage and branches of larger vegetation. Increasing temperatures cause a shift in foraging behavior to shady and cooler microclimates, and activity slows during hot afternoon temperatures. Almost all water is obtained from food, and free-standing water is rarely used even when found .

Calandra Lark - It is mainly resident in the west of its range, but Russian populations of this passerine bird are more migratory, moving further south in winter, as far as the Arabian peninsula and Egypt. It is a very rare vagrant to western Europe.

Calayan Rail - The Calayan Rail is one of the 20 known extant flightless rails. It is small and dark brown, with a distinctive orange-red bill and legs, and utters loud, harsh calls. Its habitat seems to be restricted to forests on coralline limestone areas on Calayan and extends to a total of less than 100 km². Biologists estimate that there may be 200 pairs on the island.

California condor - Species-level:

California creeper - Adults are brown on the upperparts with light spotting, resembling a piece of tree bark, with white underparts. They have a long thin bill with a slight downward curve and a long tail. The male creeper has a slightly larger bill than the female. The Brown creeper is 11.7-13.5 cm long .

California Gull - Adults are similar in appearance to the Herring Gull, but have a smaller yellow bill with a black ring, yellow legs, brown eyes and a more rounded head. The body is mainly white with grey back and upper wings. They have black primaries with white tips. Immature birds are also similar in appearance to immature Herring Gulls, with browner plumage than immature Ring-billed Gulls.

California pygmy owl - Some experts consider this bird a superspecies with the Mountain Pygmy Owl. The American Ornithologists' Union, the authority for the North American region, does not recognize this split, so the populations are still considered conspecific. Clear differences in the territorial calls by males are the basis for a proposed split, with birds in the high elevations of Arizona and Mexico giving a two-note call while their more northerly congeners give a repeated single-note call. Results from DNA sequence comparisons of cytochrome-b have been weak and inconclusive despite being referenced repeatedly as a justification for taxonomic splitting.

California Quail - These birds have a curving crest or plume, made of six feathers, that droops forward: black in males and brown for females; the flanks are brown with white streaks. Males have a dark brown cap and a black face with a brown back, a grey-blue chest and a light brown belly. Females and immature birds are mainly grey-brown with a light-colored belly. Their closest relative is Gambel's Quail which has a more southerly distribution and, a longer crest , a brighter head and a scalier appearance. The two species separated about 1-2 million years ago, during the Late Pliocene or Early Pleistocene.

California thrasher - At about 12 inches and nearly 85 grams , the California Thrasher is the largest species of mimid. It is generally brown, with buffy underparts and undertail . It has a dark cheek pattern and eye-line, and unlike most thrashers, has dark eyes.

California Towhee - The taxonomy of this species has been debated. At the higher level, some authors place the towhees in the family Fringillidae. Within the group, there has been debate about whether the distinction between this species and the similar Canyon Towhee, Pipilo fuscus, should be at the specific or subspecific level. The two populations are quite isolated from each other, and molecular genetics seems to have settled the matter in favour of two distinct species for the present. On the other hand there seems to be little distinction between the northern and Baja Californian populations within P. crissalis.

Calliope hummingbird - These birds have glossy green on the back and crown with white underparts. Their bill and tail are relatively short. The adult male has wine-red streaks on the throat, green flanks and a dark tail. Females and immatures have a pinkish wash on the flanks, dark streaks on the throat and a dark tail with white tips.

It is sometimes considered conspecific with the Brown Teal. The plumage is similar to that of the Auckland Teal, dark sepia with the head and back tinged with green iridescence, and a chestnut breast on the male, with the female dark brown all over. Its natural habitat is tussock grassland dominated by Poa tussock grass, ferns and megaherbs. The species also uses the burrows and pathways of petrel species that nest on the islands. They are apparently territorial in the wild, and probably feed on amphipods and insects.

Campo Miner - The Campo Miner is a species of bird in the Furnariidae family. It is found in Bolivia, Brazil, and Paraguay. Its natural habitat is dry savanna. It is threatened by habitat loss.

Campo Oriole - It is found in Argentina, Bolivia, Brazil, Colombia, Ecuador, Guyana, Paraguay, and Peru.

Canyon wren - Similar to the Rock Wren in habitat and habits, the Canyon Wren prefers rocky environments near water, particularly in fairly dry country and steep terrain . It feeds on insects and spiders by probing into crevices with its long bill. Its coloration is rustier than that of the Rock Wren, even on the belly, with a contrasting white throat and breast. The Canyon Wren is more often heard than seen, and its falling series of whistles is one of the more familiar bird calls of the canyons of the western United States.

Cape Cormorant - It breeds from Namibia south to southern Cape Province. In the nonbreeding season, it may be found as far north as the mouth of the Congo, and also extends up the east coast of South Africa as far as Mozambique. In the 1970s, the breeding population was estimated as over 1 million in Namibia alone. However, the IUCN now classifies it as "Near Threatened" on the grounds of: ongoing pollution from oil slicks, disturbance to stocks of its prey, and pathogen or parasite increases.

Cape Eagle-Owl - There are three subspecies: capensis , mackinderi , and dilloni . The distribution of all three is patchy. The subspecies mackinderi, which is slightly bigger than the others, is sometimes split as Mackinder's Eagle-owl, Bubo mackinderi.

Cape Francolin - The sexes are similar in plumage, but the male has two leg spurs whereas the female has at best one short spur The juvenile is similar to the adults, but has duller legs and clearer vermiculations. This large dark francolin is unlikely to be confused with any other species in its range.

Cape Gannet - They are easily identified by their large size, black and white plumage and distinctive yellow crown and hindneck. The pale blue bill is pointed with fine serrations near the tip; perhaps because of the depth and speed of the gannet's dive when fishing , its beak has no external nostrils into which the water might be forced.

Cape Grassbird - The Cape Grassbird breeds in southern Africa in South Africa, Lesotho, Mozambique and Swaziland with an isolated population in eastern Zimbabwe.

Cape Longclaw - The Cape Longclaw is a 19-20 cm long. The adult male has a grey head with a buff supercilium and a streaked blackish back.

Cape Siskin - This species is sometimes considered to be conspecific with the Drakensberg Siskin, Serinus symonsi of eastern Cape Province, western Natal and Lesotho in which case the nominate western form is S. t totta, and the eastern form is S. t. symonsi.

Cape Sugarbird - The Cape Sugarbird is a grey-brown bird that easily recognizable by a spot of yellow under its tail and the very long tail feathers present in males. The male is 34–44 cm long, and the shorter-tailed, shorter-billed, and paler breasted female 25–29 cm long. Another characteristic of the Cape Sugarbird is the sound it makes when it flies. The main flight feathers are arranged in such a way that when the bird beats its wings, a frrt-frrt sound is made with the intention of attracting females.

Cape Teal - This species is essentially non-migratory, although it moves opportunistically with the rains. Like many southern ducks, the sexes are similar. It is very pale and mainly grey, with a browner back and pink on the bill . The Cape Teal cannot be confused with any other duck in its range.

However, the subspecies R. v. ariel is closer to R. v. culminatus than to the nominate, and are by some already considered close to distinct species status. As R. v. ariel was described before R. v. culminatus, if separated they would become Ramphastos ariel ariel and R. a. culminatus. There also exists an isolated population in eastern Brazil. It looks very similar to, and has traditionally been considered part of, R. v. ariel, but molecular analysis suggests that it has been isolated for a long time and is a yet-undescribed separate subspecies or possibly even species .

Club-winged Manakin - Like several other manakins, the Club-winged Manakin produces a mechanical sound with its extremely modified secondary remiges. The manakins have adapted their wings in this odd way as a result of sexual selection. Charles Darwin noted how females could cause evolutionary change simply by the influence of their mating preferences. Thus, in manakins, the males have evolved adaptations to suit the females' attraction towards sound. Wing sounds in many manakin lineages, however, have evolved independently. Some species pop like a firecracker, and there are a couple that makes whooshing noises in flight. The Club-winged Manakin, with its unique ability to produce musical sounds, is indisputably the most extreme example of sexual selection in manakins.

It spends most of its time at sea, only coming to land to breed on rocky cliff shores or islands.

Common Hawk Cuckoo - The Common Hawk-cuckoo Cuculus varius also popularly known as the Brainfever bird due to its call, is a medium sized cuckoo resident in South Asia. It bears a close resemblance to the Shikra, a sparrow hawk, even in its style of flying and perching. The resemblance to hawks gives this group the generic name of hawk-cuckoo and like many other cuckoos these are brood parasites, laying their eggs in nests of babblers and laughing-thrushes with the chicks brought up by the foster parents.

Common Hill Partridge - Males of the species have ornate patterns and markings, a combination of an orange crown and face set against a black head and streaked throat. Females lack the head markings but share the variegated wings and grey-streaked underparts of the male. Four subspecies have been identified on the basis of differences on the head markings on the male. The food of this species comprises seeds and various invertebrates, which it collects by scratching in leaf litter. The birds are mostly seen in pairs or small coveys of up to 10 individuals that may be made up of family groups.

Common Iora - During the breeding season, the male performs an acrobatic courtship display, darting up into the air fluffing up all his feathers, especially those on the pale green rump, then spiralling down to the original perch. Once he lands, he spreads his tail and droops his wings.

It is strongly migratory and winters south of its breeding range to the equator. Unusually for a bird with such a large range, it has no geographical subspecies if the possibly conspecific Eaton's Pintail is considered to be a separate species.

Common poorwill - Many northern birds migrate to winter within the breeding range in central and western Mexico, though some remain further north. Remarkably, the Common Poorwill is the only bird known to go into torpor for extended periods . This happens on the southern edge of its range in the United States, where it spends much of the winter inactive, concealed in piles of rocks. This behavior has been reported in California and New Mexico. Such an extended period of torpor is close to a state of hibernation, not known among other birds. It was described definitively by Dr. Edmund Jaeger in 1948 based on a Poorwill he discovered hibernating in the Chuckwalla Mountains of California in 1946.
